I was not a big fan of the tiles either. But I think you just need to get used to it~
Mass Heal is kind of bad in the way it works. The skill is an instant aoe circle (kind of small) but only for people in front of you. Basically your toon will “throw” its skill in the front, so only people who are in front of you and not too far (+ you) will get healed.
Problem with that is the cooldown: 30 seconds, and no overheat.
So you can’t spam it.
And in a party, it’s kind of hard to keep people grouped and not moving around everytime you want to heal. If it’s your main heal, when it’ll miss some people, you’ll be a bit scr*wed.
If you want to keep a level 5 Healing, I’d say not to max Aspersion and put extra points in Revive instead.
Revive is great, especially if you don’t go too massive on Healing. And a low level one is kind of “useless” since the person who’ll revive will have high chances of dying again right away (because of the low HP and invincibility duration after the resurrection).
Mass Heal, in my opinion, is more of a “last chance” heal.
The tiles are, in the end, easier to use (especially if you got it to 10) because better cooldown, overheat, and they stay on the ground quite a long time. So your teammates can use them again if they need.
For your second build (eee), you don’t need Simony. Your previous circles will be Priest and Cleric, so you won’t have many good skills to turn into scrolls.
